1996 tacoma 3.4--What year engines will fit?

Hello to all. I have been driving Toyota trucks for over 11 years now, and I have run a body shop for 19 years so I have some experience in the field. I recently purchased a 96 Tacoma 4X4 ext cab with the 3.4L. Like so many others it had bad head gaskets, and I think the previous owner let it get hot (probably many times), and probably cracked the heads. When I bought it there was water in the oil and it was chuggin' tons of white smoke. But the price was right so I limped it home. Well she locked up in my driveway so instead of rebuilding the heads I am just going to try to find a used engine. I know that the 3.4s are the same from 95 to 99, but the block is the same up to 04. My question is, what is the difference in the 2000 to 2004 engines? Are the heads completely different or is it just the electronics and maybe intake?

Thank you in advance for any answers!

i heard of a guy putting an LS1 in his truck, but idk about the engine differences.

 

I don't think anyone's done it on a 4x4 before.

 

Actually, head gasket issues on the 3.4L are very uncommon. Its predecessor however, the 3.0L, is a different story.

The 3.4L was basically unchanged from the '96s thru the '04s.

 

Thanks for the replies.

I am not looking to do an engine swap with anything other than another 3.4. But apparantly something is different in the 2000-04's. I know the blocks are the same but I was hoping the heads are as well.

Thanks!

 

Everything is the essentially the same except the ignition/spark system I believe. You can get a 3.4L from 96-04 and it'll be good.

 

This, all the 3.4l are the same except for EGR was on some and not on others.

Nothing major tho.

Swaping a new used one it will be easy.

 

Thanks so much for the replies! I hope you guys know what your talking about because I am about to purchase a 2004 engine tomorrow.

 

Did the 2004 motor swap over fine???

 

Older thread, but Im also curious on whats different. Putting a 04 motor in my 96 on a few weeks

 

I guess I should have actually read all the replies lol. Thanks man!

 

lol it's all good.

 

the engines are the same but many accessories are very different. The idle up for P/S is vacuum in 96, the tps conection is different, etc. I would just use the block and intake but switch all the accessories over from your 96 to make life easy on yourself.

 

here is a 99 v 96 tb with tps from a 3.4
99


96

 

If you have an early one the evap system could be completely different as well with a round can instead of the multi ported box with map sensor. Pay special attention to all the routing as the vac system is going to be completely different between the two, including some of the hard lines attached to the intake

 

Hmm intersting. Good to know, thanks for the info!

 

Just swap your intake and exhaust over to any year motor and you'll be good. That an PS I guess on earlier trucks.

 

That's the plan. Pull my old intake and exhaust. Love your truck and your trip report by the way. And next time you come out to BC, you gotta come to Vancouver Island!

 

Is there some wheeling trails on the island?
